Global Copper Reports Further Step Out Drill Results at Relincho Including 544 and 422 Meters Grading 1.20% and 0.83% Copper Equivalent

Results include 188 meters grading 2.07% Copper Equivalent

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Dec. 10, 2007) - Global Copper Corp. ("Global") (TSX:GLQ) announces results from a further ten holes in the sulphide drilling program at its Relincho copper-molybdenum project in Chile. Six of the holes were step-outs in the Las Guias area, two were drilled at Marja and one was drilled to connect these two areas. Additionally two holes stepped out on the southern and eastern margins of the Relincho deposit. Results are highlighted by step-out holes RG06-133 which intersected 544 meters grading 0.70% copper and 0.084% molybdenum (1.20% copper equivalent(ii)) including 188 meters grading 1.07% copper and 0.167% molybdenum (2.07% copper equivalent(ii)) and RG06-212 that returned 442 meters grading 0.62% copper and 0.035% molybdenum (0.83% copper equivalent(ii)).

These drill holes further expand the zone of breccia-hosted copper-molybdenum mineralization defined by drilling at Las Guias to date. Mineralization is focused along the contact zone of a porphyry copper intrusion that does not crop out and remains open to the northeast, south and to depth. The intrusion defined to date is elongate northwest-southeast and approximately 700 meters long and 300 meters wide. The latest drill results are shown in the table below. There is insufficient geological data to calculate true thicknesses of these intervals.

To date 74 holes totaling 41,850 meters have been completed in the sulphide drill program. Four diamond drill rigs are now operating on the property and the drill program is now forecast to continue well into 2008. A new NI 43-101 mineral resource estimate will be completed soon and will include the results of the sulphide drill program to date allowing for a Preliminary Economic Assessment to be initiated in the first quarter of 2008.

(i) Diamond drill holes have been drilled from the bottom of previously
drilled RC holes (pre-collars). For that reason the number of the
pre-collar is not the actual order in which these holes were drilled as
part of the sulphide program. The first column indicates the sequence
in which the sulphide holes were drilled.
(ii) Copper equivalent is calculated for primary sulphide intervals using
US$1.00/lb Cu and US$6.00/lb Mo and is not adjusted for metallurgical
recoveries as these remain uncertain. The formula used is as follows:
CuEQ equals Cu% + Mo% x 6.All intervals are in sulfide mineralization
unless otherwise noted.

The technical reports for the previously delineated oxide and sulphide resource estimates can be viewed on both the Global website at and SEDAR at
